Diabetes is seriously hazards to human health and its pathogeneses are not clear. Recent studies show that the imbalance of intestinal flora and the development of diabetes are closely related. Appropriate bacteria can improve blood sugar disorder. Treating diabetes from the theory of Pi-Wei is effective. Regulating intestinal flora has become a new pathway for treating diabetes from the theory of Pi-Wei. On the basis of intestinal flora, authors discussed the treatment of diabetes from Pi and Wei.

OBJECTIVETo observe the effects of signal factors of corticosterone (CS), cAMP, cGMP, Ca2+ andprotein kinase C (PKC) on lymphocyte apoptosis in mouse thymus induced by X-rays of 4 Gy in vitro.

METHODSThe DNA lytic rate for thymocytes was measured by fluorospectrophotometry.

RESULTSThe DNA lyric rate for thymocytes 4-8 hours after irradiation with 2-8 Gy was significantly higher than that in the control (P<0.01). As compared with the control, the DNA lytic rate for thymocytes treated with 0.01 micromol/L CS (P<0.01), 50 ng/mL cAMP (P<0.01), 0.05-0.4 microg/mL ionomycin (Iono, P<0.05 or P<0.01) or 0.05-0.4 ng/mL phorbol myristate acetate (PMA, P<0.05 or P<0.01), respectively, was significantly increased, while the rate for thymocytes treated with 50 ng/mL cGMP was not significantly increased. The DNA lytic rate for thymocytes treated with 0.01 micromol/L CS (P<0.01), 50 ng/mL cAMP (P<0.01), 0.2 and 0.4 microg/mL Iono (P<0.05), and 0.2 and 0.4 ng/mL PMA (P<0.05) plus 4-Gy irradiation, respectively, was significantly higher than that treated with single 4-Gy irradiation, while the rate for thymocytes treated with 50 ng/mL cGMP plus 4-Gy irradiation was not increased. When both 0.4 microg/mL Iono and 0.4 ng/mL PMA acted on the thymocytes, the DNA lytic rate for thymocytes was significantly higher than that in the control (P<0.01), the DNA lytic rate for thymocytes treated with both 0.4 microg/mL Iono and 0.4 ng/mL PMA plus 4-Gy irradiation was significantly higher than that treated with single 4-Gy irradiation (P<0.05), but was not significantly higher than that treated with 0.4 microg/mL Iono plus 4-Gy irradiation or 0.4 ng/mL PMA plus 4-Gy irradiation.

CONCLUSIONCS, cAMP, Ca2+, and PKC signal factors can promote thymocyte apoptosis induced by larger dose X-rays.

OBJECTIVETo explore the changes of cycle and apoptosis of spermatogenic cells and antioxidant capacity of the serum and testis in male rats with diabetes mellitus.

METHODSThirty male rats were divided into two groups, 10 for normal control and 20 for the diabetes group. The rats were injected intraperitoneally with streptozocin (TZ) to develop diabetes, and 12 weeks later, their survival rate and testis weight were recorded. The percentage of G0/G, S and G2/M phases and apoptosis in spermatogenic cells were measured with flow cytometry (FCM). Malondialdehyde (MDA) and nitric oxide (NO) levels, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and NO synthase (NOS) activities in the serum and testis were measured with thiobarbituric acid reactive substances (TBARs), nitric acid reoxidized enzyme, xanthine oxidative enzyme, 5,5 Dithiobis (2,2 nitrobenzoate) (TNB) and visible light photometer methods, respectively.

RESULTSTwelve weeks after the male rats got diabetes, their survival rate, body weight and testis weight were significantly lower (p < 0.05), and the percentages of G0/G1 phases and apoptotic spermatogenic cells were obviously higher (P < 0.05) than the normal control. At the same time, the percentage of S and G2/M phases spermatogenic cells decreased. So the spermatogenic cells were arrested in G0/G1 phase. In the diabetic rat serum and testis, especially in the testis, MDA levels were distinctly higher and SOD activities were significantly lower than those in the control. Serum GSH-Px activities of the diabetic rats were significantly lower (p < 0.05), while testis GSH-Px activities were significantly higher than those in control group (P < 0.01). NO contents in the serum and testis of the diabetic rats (P < 0.01) increased significantly, particularly the former, while NOS activities in the serum decreased significantly as compared with the control (P < 0.5).

CONCLUSIONThe increase in testis and serum MDA levels and NO contents and the decrease in the antioxidant enzyme activity of the diabetic rats may be relevant to spermatogenic disorder caused by the increase of G0/G1 phases arrest and spermatogenic cells apoptosis.

OBJECTIVETo screen mutations of tuberous sclerosis complex (TSC) patients to confirm a clinical diagnosis of TSC, and to perform prenatal diagnosis for families with mutations.

METHODSIn this study, PCR-denaturing high-performance liquid chromatography(DHPLC), supplemented with sequencing when necessary, was used to screen TSC1 and TSC2 mutations in 21 patients from 19 pedigrees visited author's hospital in the last five years. For novel mutations, one hundred unrelated healthy individuals were screened to exclude the possibility of polymorphism.

RESULTSSeventeen different mutations were found in 21 patients of 19 pedigrees with 13 being novel mutations, including c. 2672delA, c. 2672insA of TSC1 gene and c.4918insCGCC, c.1143delG, Intron27+1 G>A, c.1957-1958delAG, Intron5+1 G>A, c.910insCT, c.2753 C>G, c.4078dupAGCAAGTCCAGCTCCTC, Intron 11 -1 G>A, Intron 14+1 G>A, c.684 C>A of TSC2 gene, indicating a high frequency of de novo mutations in TSC. Three of these mutations were in the TSC1 gene (N762S, c.2672insA and c. 2672delA), while all remaining 14 were in the TSC2 gene. Prenatal diagnosis for TSC was performed for 7 fetuses from these pedigrees. The six fetuses that tested negative for TSC mutations were carried to term and, to date, none of these children has shown symptoms of TSC.

CONCLUSIONAuthor's data showed that a mutation detection rate of tuberous sclerosis was 89.5%(17/19) among patients in author's hospital. The ratio of TSC2 and TSC1 mutations was about 1:1 in the familial cases, but TSC2 mutation was more common than TSC1 mutation in sporadic cases. Author's data demonstrated that birth of TSC children for those with familial history of TSC could be prevented through prenatal diagnosis.

OBJECTIVETo study the effects of different compatibility proportion of Jiaotai pills on treating type 2 diabetes mellitus (T2DM) in rats.

METHODThe model of type 2 diabetes mellitus in rats was established by injecting streptozotocin from tail vein and feeding with high fat and high caloric diet. Diabetic rats were randomly divided into model group, Jiaotai pill 1 group (Coptidis Rhizoma-cinnamon 2: 1), Jiaotai pill 2 group (Coptidis Rhizoma-cinnamon 4: 1), Jiaotai pill 3 group (Coptidis Rhizoma-cinnamon 10: 1) and metformin group. Rats in different treatment groups were given by corresponding therapy from gastric tube. Meanwhile normal control group was another set. Body weight, oral glucose tolerance test (OGTT), blood lipid level including total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C), plasma levels of free fatty acid (FFA) and adiponectin, plasma liver enzymes activity(ALT, AST, AKP, gamma-GT) and pathological results of liver tissue were determined after eight weeks.

RESULTBody weight, fasting plasma glucose (FPG), postpradial plasma glucose at one hour (PG-1 h), postpradial blood glucose at two hour (PG-2 h), plasma levels of TC, TG, LDL-C, FFA and liver enzymes activity were all increased in rats of model group compared with those in normal control group. Plasma levels of HDL-C and adiponectin were decreased in model group (P < 0.01). Fatty degeneration of hepatocytes was apparent in liver tissues in rats of model group. Compared with model group results of OGTT, blood lipid levels and liver enzymes activity were improved while levels of HDL-C and adiponectin were increased in rats of different treatment groups (P < 0.05 or P < 0.01). Meanwhile fatty degeneration of hepatocytes was improved in liver tissues in rats of different treatment groups. Compared with metformin group, plasma level of HDL-C was elevated while AKP and gamma-GT were decreased significantly in rats of Jiaotai pill 1 group (P < 0.05), gamma-GT level was decreased significantly in rats of Jiaotai pill 2 group (P < 0.05), AST, AKP and gamma-GT levels were decreased significantly in rats of Jiaotai pill 3 group (P < 0.05). Compared with Jiaotai Pill 1 group, plasma levels of HDL-C was decreased while AKP levels was elevated significantly in rats of Jiaotai pill 2 group, but HDL-C was decreased in rats of Jiaotai pill 3 group (P < 0.05).

CONCLUSIONIt is suggested that different compatibility proportion of Jiaotai pills are effective on treating type 2 diabetes mellitus in rats. The effect of Jiaotai pill 1 group is better than that of other therapy groups.
